M. H. GOULD ICE CREEPER No v. 24, 1936.

Filed'March 29, 1934 Patented Nov. 24,: 1936 UNi'l-ED STATES PATENT OFFICE ion-camera r Merton n. Gould. Dover-Foxcroft, Application March 29,1934, Serial No. 118,015 1 Claim. (01. 24-110) This invention relates to anti-slipping devices for vehicles and more particularly to a means to prevent side slipping of a vehicle moving over an icy surface. l 5. An object of this invention is to provide means which may be readily mounted on' or removed from vehicle tires to prevent side slipping of the wheels and also to prevent circumferential slipp i A further object of this invention-is to provide in a device of this kind replaceable memhers-carried by the attaching means so that'the side slip preventing members may. be readily replaced.

g 15, A still further object of this invention is to provide in a. deviceof this kind, means engaging over the outer surface of the tire to prevent circumferential-slipping of the tire and at the same time hold the anti-side slipping members iii). contacting relation with vthe side walls of the re.

The above and various other objects and advantages of this invention will in part be de-\ scribed and in part be understood from the following detailed description of the present preferred embodiment, the same being illustrated in the accompanying drawing wherein:

Figure 1 is a sectional view of a tire mounted on a rim and wheel having a device constructed s according to the embodiment of this invention mountedthereon. a

Figure 2 is a detail sideelevation of. the creeper members removed from the tire.

Figure 3 is a fragmentary sectional view show, ing the manner in which the device is releasably secured to the tire. Referring to the drawing wherein like charracters of reference designate corresponding parts throughout the several views, the letterT designates generally a tire which is mounted on a rim R carried by a wheel W. y

,In order to prevent side slipping and circumferential slipping of the tire T when moving over an icy or slippery. surface, I have provided a pair of side plates l0 having wing portions H,

each provided with an aperture l3 to receive an end link l2 of a cross chain ll en aging over the outer surface of the tire T. v The plate l0 is disposed on one side of the tire T and has at substantially its central portion and adjacent the inner edge thereof an elongated. opening IS ,in which the looped 'end I6 of a strap I1 is secured.

The upper or outer end III of the plate I0 56 has secured thereto a toothed plate l9 secured the tire opposite'from the plate I and is con- 10 structed substantially similar to the plate l0 having a slot l5 therethrough to receiver the other end of the strap ll which is' passed through the opening I5.

The wing portions ll' of the plate l0 each 15 have an aperture l3 therein to receive the end link l2 of the cross chain H. An anti-side slipping plate member I9- is secured to the extension l8'- of the plate ID as by rivets or securing members 20', and the body 2| of. the 20 member I9 is curved in conformity with the curvature of the extension l8 which fits snugly against the side of the tire. The teeth 22' are similar to the teeth 22 and are curved outwardly or reversely from the body 2I'," 25

.The plate J0 has a substantially U-shap'ed strap locking member, generally designated as 23, which has the free legs 24 thereof mounted on a roller or pin 25, the ends of which are secured to L-shaped bracket members 26 carried by the plate 30 Ill. The bight 21 of the locking member 23 is disposed substantially coincident with the outer edge or margin of the opening l5 and this bight has its outer edge portion provided with teeth which are adapted to engage the strap l'l so as to 5 I 3i provided in the confronting leg 24 of the locking or holding member 23.

The device hereinbefore described is applied by placing the cross chains M on the outer surface 45 or tread of the tire T with the plate "I engaging against one side wall of the' tire and the plate l0 engaging against the opposite side wall. The strap I1 is passed between spokes of the wheel W and threaded into the opening I "andthen pulled in a manner to tighten the d vice on the tire --whereup0n the free'end of the strap I1 is passed over the teeth on the holding member 21 and then threaded between the roller 25, whereupon the free end is looped inwardly and re-threaded be- 5s tweenthe roller 2! and the first portion of the strap threaded between this roller and the plate I 0'. The latch 28 will maintain the locl:in,, member 23 in operative position so that it will not be displaced during the rotation of the wheel.

What is claimed is: t In a device of the character described, a buckl for securing the relatively free end of a fastening strap, the same comprising a. plate having an opening formed therein for the passage 01 the end of the strap therethrough, bracket members carried by said plate, a pin connected to said bracketmembers, a U-shaped locking member swingably mounted on said pin with its cross-bar adapted to extend across said opening and having an aperture formed in one of its side arms, said cross bar being adapted to engage the relatively free end of the strap when the latter is passed through said opening, and a spring-pressed latch carried by said plate to one side of said locking member and adapted to enter the opening in said locking member when the latter is in.lockln'g engagement with the strap, as and for. the purpose w set forth.
